Credit for the translation goes to Paola D'Andrea.
Many thanks also to http://www.crowdin.com: not only they offered a lovely translation platform free of charge, but they were also very patient and supportive. Crowdin asked me to officially invite Linux Mint to host their User Guide translations there for free. I can only recommend them, because of the fun interface and all the underlying magic that allowed us to easily setup and manage the project, while focusing on the translation itself.

For comments, suggestions or just to say hi you can reach us at mint-ita (at) edlabs.it.

As for Crowdin, you'll have to ask Clem about that. You can contact him at the development team email (http://www.linuxmint.com/contactus.php). May take a while for a reply, especially with LMDE 2 in RC phase right now Alternative is to join #linuxmint-dev IRC channel on spotchat network and find Clem there.
